Lower temps = More stablity?

[Trashcan]

So I just added waterblocks to my 660tis and I've been able to OC ALOT higher. So far im at 1346mhz running unigine valley for about 2hrs with max temp at 33C. So does having lower temps increase stability?

[PillowSmoke]

Yes in terms of maintaining the clock, and no hit with thermal limits.

[TheRuke]

Yes.

[Oshino Shinobu]

Pretty much, yes.

33 °C under load is pretty impressive. keep pushing but don't put voltage too high .

Dahm that is really impressive! my 270x gets 70C aircooled while just gaming!

Voltage is stock 1.175

They're only 660's, their tdp isn't really that high for the temps to raise more than that.   But yeah 33c is quite good

They're 660 Tis that's a big difference. But still not much heat to be produced, that's right. But as OP has said Voltage is still stock. I'd suggest going to at least 1.2V and in small steps up to 1.3V. It's free performance, what can go wrong?

only if you have a good gpu in the first place. it does help but only up to a point. what do you have your memeory clocked at? the memory overclock is more important than the core clock in valley.

Yeah, I'm unsure if their voltage levels are like 780s, the stock is 1.175 like he has em at now,  I managed to get 1.3v bios for my 780s, from what I've seen it's about a 1:1 ratio from extra mv to core clock speed.  

 

With 1.2v I was getting ~1208-1220 core clocks, and with 1.3v that I can use now I get about the same.   If his temps end up being the same ratio that mine went up, he should only see about a 1-3 degree difference from 1.2 to 1.3v 

 

Usually in games I was at 36 before the 1.3v bios, now they hover around 37-38, with 1300-1320. 

 

If he's already at 1346 he should be able to get dam near close to 1500 if he could find a new bios for them or if they're already unlocked voltage.  I think he got pretty lucky

 

I think he should be safe at 1.3v if he's only doing it every once and awhile for a day or two of gaming, and then running them at 1.225-1.25v 24/7.

But then again, that's all up to him
